Water Filter not working

[MichMich]

Systems in question:

1) 3M™ Aqua-Pure™ Under Sink Dedicated Faucet Water Filter System AP-DWS1000

2) Samsung fridge with ice make and purified water

Hello!

This morning there was no water flow from my sinks water filter faucet and no water flowing from my Samsung fridge neither.

I think (not sure) that my fridge draws water from the 3M filter system, pipes are in the attic? Not sure.
I've just replaced 2 filters this last September.
System worked fine yesterday.

Any clues what happened?

Should I troubleshoot or just replace the (8 year old+) system?

Just called 3M.
Possible issues:
1) clogged filters, need to remove and check O rings,
2) re-set the filter change indicator timer, could be in OFF position.

I'll update tomorrow, once I get home to do above 2 steps.
